Ovulation tests!

Hey guys so I had a chemical pregnancy on March 9th 2021, and since then obviously I know things become out of whack, (I usually Ovulate on CD 12-13 like clock work before) this time on CD 16 I got this real dark line but my clear blue advanced was empty!

Today on CD 18 I got the blinking smiley face for “high fertility” has anyone had this happen or are the cheapies just not really reliable compared to clear blue advanced obviously, and is it normal to ovulate on CD 20 by the time this goes to peak? Thanks!
